I Application filed April 19, 1917. Serial No. 163,103. 1

To all whom it may concern skilled in the art in the light of the follow ing explanation of the accompanying drawings illustrating what I now believe to be the preferred mechanical expression or embodiment of the invention from among other forms within the spirit and scope thereof.

The object of the invention is to provide certain'improvements in packing strips and the like composed of series of flexibly connected collapsible 0r expansible cells. j

The invention consists in certain novel features in construction and in combina-' tions and arrangements as more fully and particularly set forth and specified hereinafter.

. My present invention is characterized, in whole or in part, by collapsible cells, each composed of a flexible folded sheet, flexibly hinged or connected together to form a strip by securing an end or edge portion of the sheet of a cell to the wall of the next cell.

Referring to the accompanying drawings: Figure 1 is a perspective view of a portion of a strip showing several of the con-' nected cells thereof expanded.

Fig. 2 is a detail perspective view of one of the individually complete cells detached from the strip.

Fig. 3 is a section on the line 33, Fig. 1.

Fig. 4: shows the sheet forming a cell, detached and flattened out.

In the particular embodiment illustrated, each cell is composed of an approximately rectan lar sheet 1 of suitable flexible material such as, paper or any other sheet material possessing the required characteristics) suitably folded to bring its end or edge portions together which edge portions are secured together to form an individually complete open end tube, although I do not wish to limit all features of my invention to cells or tubes, each of which is open at both ends.

This sheet 1 is folded on the'spaced parallel longitudinal fold lines a, a, to provide the central panel 2 forming the closed side 1 wall of the cell and to provide the opposite overlapping end portions or panels 3, 4, forming the opposite or multiply side wall of the cell and preferably secured together, as by adhesive 8. The outermost of these two overlapping sheet portions 4 has its edge portion free or extended to form a connecting or hinge flap or edge portion 5 by which the cell is flexibly secured to the next adjacent cell in the formation of the strip by'suitable means such as adhesive 7 The innermost or onderlying panel 8 of the multiply sidewall of the cell extends approximately throughout the full Width of said wall and the outer surface of the end or edge portion 6 thereof is secured to the inner surface of the outer panel 4, by the longitudinal stripe of adhesive 8 so as to leave the flap 5, free and disconnected from the adjacent outer surface of panel 3. p

The cells are united to form the completed strip through the medium of adhesive material 7 (or other securing means) securing the outer surfaces of flaps 5 of the cells to the outer surfaces of the single ply walls 2 of the adjacent cells to one side of the longitudinal center lines of walls 2. In the completed strip, the cells are preferably similar and parallel with their single ply walls 2 all facing in the same direction and with their multiplywalls arranged beside the single ply walls of the adjacent cells and united thereto by the flaps 5 which constitute flexible or hinge connections between the cells and on which the strip can flex or bend in either direction whenbeing rolled into a coil for insertion into a statutory container for.

cigars, after each cell has been supplied with a cigar and thereby expanded. However, the cells can receive and hold other articles than cigars, and can be used for containing and packing various articles in boxes or other containers.

If so desired, the adhesive 7 for uniting l the cells, can be applied in a comparatively narrow stripe on and longitudinally of the outer surface of panel 3 of each cell and 'hence secure the single ply wall 2 of each cell to the flap 5 of the adjacent cell, or in j the process of manufacture, a continuous tube'can be produced, such as described,

' thereof or to the flaps 5, and this tube can with the overlapping panels united by adhesive 8, and a stripe of adhesive can be applied to the outer surface of the single ply wall 2, to one side of the longitudinal center open thecells, as shown, or'can be comends of the cells' can be slit, notched or other-' I pers of cigars whcn being inserted fin; the

invention and hence I do not wish to limit posedofa single folded flexible sheet se-w pressed to collapse orclose the packing and shipment. T If'so desired, the edges of the sheets at the cells, 5 for:

wise formed, to prevent injury to the wrapcells. 1

It is evident that various changes and r modifications might bevresorted to without departing from the spirit and scopejof my myself to the exact disclosure What I claim is 1. A flexible packing stripcomposedfofa', series of united collapsible cellsyeach comcured together at its opposite edge-portions? I the series.

to provide'a single connecting flap which is" secured to the side wall of the next cell of 2. An expansible packing strip composed of a series of united collapsible parallel individually-complete cells, each cell consisting of a flexible sheet folded with its edge portions overlapping and one projecting to form a connecting flap, the connecting flap [of each cell secured to the adjacent wall of the next cell of the series. I v

3. A packing strip composed of a series of united expansible cells, each cell consisting of a flexible sheet folded to form a single ply side wall and an opposite multiply sidewall, the outer ply of said last mentioned wall forming a connecting flap, said Iflaps of the series. a

I cells being. united to the next cells in the a 4.1Apacking strip composedof a series of united expansible cells, each cell composed I of a flexible sheetifoldedonitself'with its ends overlapping -'to form a single ply side I j wall and a multiply side wall, the end of the outer ply of said last mentioned wall forming a flexible connecting flap, said flaps of the cells being secured to' the adjacent single ply walls of the next cells of the series, the end of the inner ply of each multiply lwall being secured to the outer ply. y

1 5., An .expansiblepacking strip composed of a plurality offiexible sheets, one end of y ".each' sheetsecured to an intermediate'pon tion'of the next'sheet'to one side ofthe centerflongitudinal line ofthe sheet, each sheet being folded to form a flat cell'with the other'end of the sheetlforming an inner ply behind said secured end.
